There really is some charm emulating games on weak hardware like the GBA, even if it's far from ideal. I'm emulating this game off of my Everdrive using SMSAdvance.
Yeah, I know that the original Phantasy Star got an official GBA port, but that version had broken RNG.
@icedquinn The transparent plastic is actually a replacement shell. The original shell was blue (non-transparent), but it was cracked so I replaced it. In fact, I don't think there were any GBA SPs that (officially) had transparent shells.
